As reported by Eugene, the practice of sizing the address space in the virtual memory system based on the maximum address in the table passed to ArmConfigureMmu() is problematic, since it fails to take into account the fact that the GCD memory space may be extended at a later time, both for memory and for MMIO. So instead, choose the VA size identical to the GCD memory map size, which is based on PcdPrePiCpuMemorySize on ARM systems.
